Does flowers of sulfur clean the blood?

When I was a boy in the 1950's I lived in a farming community, the old folks used a spring cleanse which consisted of equal parts of Flowers Of Sulphur and Molasses mixed together. We would take a good teaspoon every morning for several days and it did appear to work, I can't say it cleansed the blood, but, judging from the odor when one of us went to the toilet, it did something - the smell was awful.
